Throughout the 1970s, the cities in and around Galveston County, Texas were haunted by the brutal murders of eleven teenage girls. Journalist Lise Olsen and retired police detective Fred Paige are revisiting these cases after discovering a confession letter from inmate Edward Harold Bell, who is currently serving a 70-year sentence for an unrelated murder. In his chilling confession, Bell describes some of the girls’ deaths in gruesome detail and refers to many of the victims by name. Yet in the investigators’ exclusive face-to-face interviews with Bell, he denies the written confession, proving that linking him to the 45-year-old murders will be a formidable challenge. With a parole hearing for Bell looming this fall, Olsen and Paige must try to piece together evidence that demonstrates a definitive link between the convicted killer and girls he calls ‘the eleven who went to heaven’ before he has the possibility to walk free.
